This paper presents the design of a hexagonal slotted circular flexible textile microstrip patch antenna that is used for C-band satellite communication applications. In the proposed antenna design, a textile material blue Jeans fabric with relative permittivity 1.67, loss tangent of 0.01 and the thickness of 1 mm is used as the substrate with an overall dimension of 40×38 mm2. The textile material is used as it is washable, wearable, flexible and very economical. Self-adhesive Copper tape is used to make the patch and ground of the antenna that is fed through a microstrip inset feed line. The proposed antenna contains a hexagonal-shaped slot on the patch and a partial ground configuration for getting better bandwidth and gain. The antenna has been designed and simulated using CST microwave Studio software. The simulated antenna performance parameters like return loss, bandwidth, VSWR, gain, efficiency, radiation pattern and surface current are presented. The antenna is resonating at 4.28 GHz and operating in the frequency range of 2.91 -5.2 GHz, with reflection coefficient of -24.42 dB, and a bandwidth of 2.29 GHz. The peak gain of the antenna is 3.42 dBi and radiation efficiency of 87.3% at 4.2 GHz. The proposed antenna covers C-band and with its compact size, wearability and wide bandwidth capabilities, the antenna proves to be a suitable candidate for C-band satellite communication applications .
